Definitions

  • the notched wire which has been made brittle can be easily and smoothly broken off at the notches, with the position of the smooth break surface, which corresponds to the surface structure of the break, being precisely determined by the notches. Since the hinge pin, when it is broken off from the hard wire, neither changes in its shape nor in its dimensions, it can effortlessly and at high speed be inserted into the intended position in the needle and is then securely arrested or fixed there by suitable means. Since the hinge pin is hard, it does not tend to grab when it is pressed into the associated bore. Small drilling inaccuracies are compensated and equalized automatically when the smooth and hard pin is pressed in.
